alt Hacker NewsHabe you tried nextcloud + memories app? Every metadata is stored in EXIF and the directory structure on disk defines the directory structure in the app (and vice versa). When you want to move your tooling or just do things manual again, grab the disk and your are ready.
People are really sleeping on nc memories, does all the good things but none of the "I decide how your images are stored and nothing else should touch them" that immich does.
When I checked half a year ago memories (with the nc ecosystem) was still ahead in terms of features (gallery specific), albeit object tagging is rather crap in nc (faces better)
